波纹管背压平衡安全阀

待议 分享

一、波纹管背压平衡安全阀 产品概述

WA42Y波纹管背压平衡安全阀适用于存在变动背压和易燃的空器设备或管路系统,作为安全保护装置。波纹管背压平衡安全阀的波纹管部位能保护弹簧等零件腐蚀,增加产品使用寿命。

波纹管背压平衡安全阀顾名思义就是一种安全保护用的阀门,其启闭件受外力作用下处于常闭状态,设备介质压力升高,超过规定值时自动开启。波纹管背压平衡安全阀通过向系统外排放介质来阻止管道或设备内介质压力超过规定数值。波纹管背压平衡安全阀系统压力不超过允许值,使系统不因压力过高而发生事故,使增加的介质压力降低。

二、波纹管背压平衡安全阀 产品特点

1、不锈钢成形波纹管设计,可使介质不外漏;
2、平衡安全阀出口的背压,使整定压力的准确;
3、整定压力偏差小,可达±3%;
4、启闭压差≤10%;
5、选用优良的弹簧钢;
6、平面结构的阀瓣和阀座易于维修和重新加工;
7、整定压力范围大:0.06~9.0MPa;
8、调节圈结构,回座压力可调;
